Centroid offers its A590 5-axis machining center. "Weighing in at 23,000 lbs. the new A590 combines quickness and accuracy with a large worktable, high material removal rates and heavy part weight capacities with an easy to use operator CNC control interface featuring the latest CNC software," said a company spokesperson.

The A590's B-axis rotates 90° in each direction for a full 180° of movement of the tilting B-axis spindle head. The A590 accommodates workpieces up to 26.5" in diameter and 46" long with a weight of up to 2,425 lbs. The X-, Y- and Z-axes provide swift smooth movement with cutting and rapid feedrate up to 1,000 IPM.

The A590 has an optional 40 HP 16,000 RPM B-axis spindle with through-the-tool coolant and both the standard 27 HP spindle and the optional spindle are liquid cooled to tightly control thermal growth. "Equipped with a heavy duty B-axis drive, the new design allows for ultra accurate positioning at high rotational rates, which yields high metal removal rates while maintaining accuracy, tool life and providing exceptional surface finishes," added the spokesperson.

The A-axis employs a roller cam drive with high torque capacities for heavy cuts and fast rotational rates even with heavy parts. The wide machine tool base and column provide the stability needed with dual pair extra large linear ways on the Y-axis, which allow the large worktable (23.6" x 66.9") to be loaded at any point since it is fully supported. Equipped with a standard 24-position swing arm tool changer, a 40-position tool changer is optional for shops that need a large numbers of tools to complete a job.

With unlimited G-code file size, the A590 is equipped with a Centroid M400 CNC control offering fast block throughput. It is specifically designed for high feedrate, tight tolerance machining of short vector G-code created by modern CAD/CAM systems. Large part programs can be handled with ease.

The M400 is equipped with a large solid state drive and is easy to network for part program downloads and backups. "Designed for machining complex 3-D contoured workpieces the A590 holds tight tolerances with flawless blends and matches of the part geometry," said the spokesperson.
